Inference of auto-indexing jobs
When a commit of a repository is selected as a candidate for auto-indexing but does not have an explicitly supplied index job configuration, index jobs are inferred from the content of the repository at that commit.
This document describes the heuristics used to determine the set of index jobs to schedule. See configuration reference for additional documentation on how index jobs are configured.
As a general rule of thumb, an LSIF indexer can be invoked successfully if the source code to index can be compiled successfully. The heuristics below attempt to cover the common cases of dependency resolution, but may not be sufficient if the target code requires additional steps such as code generation, header file linking, or installation of system dependencies to compile from a fresh clone of the repository. For such cases, we recommend using the inferred job as a starting point to explicitly supply index job configuration.
For each directory containing a
go.mod file, the following index job is scheduled.
indexing_jobs: - steps: - root: <dir> image: sourcegraph/lsif-go commands: - go mod download root: <dir> indexer: sourcegraph/lsif-go indexer_args: - lsif-go - --no-animation
For every other directory excluding
vendor/ directories and their children containing one or more
*.go files, the following index job is scheduled.
indexing_jobs: - root: <dir> indexer: sourcegraph/lsif-go indexer_args: - GO111MODULE=off - lsif-go - --no-animation
For each directory excluding
node_modules/ directories and their children containing a
tsconfig.json file, the following index job is scheduled. Note that there are a dynamic number of pre-indexing steps used to resolve dependencies: for each ancestor directory
ancestor(dir) containing a
package.json file, the dependencies are installed via either
npm. These steps run in order, depth-first.
indexing_jobs: - steps: - root: <ancestor(dir)> image: sourcegraph/lsif-node:autoindex commands: # Yarn is used to resolve dependencies in an ancestor directory # when lerna.json configuration specifies "yarn" as the npmClient # or if the directory contains a yarn.lock file. - yarn --ignore-engines - root: <ancestor(dir)> image: sourcegraph/lsif-node:autoindex commands: # npm is used to resolve dependencies otherwise. - npm install - ... local_steps: # This is run directly before indexing if a node version can be determined # from the package.json "engines" field, or any of the files: # - .nvmrc # - .node-version # - .n-node-version - N_NODE_MIRROR=https://unofficial-builds.nodejs.org/download/release n --arch x64-musl autol root: <dir> indexer: sourcegraph/lsif-node:autoindex indexer_args: - lsif-tsc - -p - .
If the repository contains a
Cargo.toml file, the following index job is scheduled.
indexing_jobs: - root: '' indexer: sourcegraph/lsif-rust indexer_args: - lsif-rust - index outfile: dump.lsif
If the repository contains both a
lsif-java.json file as well as
*.kt files, the following index job is scheduled.
indexing_jobs: - root: '' indexer: sourcegraph/lsif-java indexer_args: - lsif-java - index - --build-tool=lsif outfile: dump.lsif
